Types Of Experiment Flashcards
What is laboratory experiment?
- A controlled environment where extraneous variables can be regulated.
- IV is manipulated and effect on DV is recorded.
What are advantages of laboratory experiment?
- EV’s can be controlled.
- Can be easily replicated.
What are disadvantages of laboratory experiment?
- May lack generalisability.
- Demand characteristics.
What is field experiment?
- A natural setting.
- IV is manipulated and the effect on the DV is recorded.
What are advantages of field experiment?
- More natural experiment.
- Participants are unaware of being studied.
What are disadvantages of field experiment?
- More difficult to control EVs.
- There are ethical issues. (Consent etc)
What is natural experiment?
Experimenter does not manipulate the IV.
-DV may be naturally occurring (e.g. exam results) or measured by experimenter.
What is advantages of natural experiment?
- May be the only ethical option.
- Greater external validity.
What are disadvantages of natural experiment?
- Natural event may only occur rarely.
